This paper presents some simple ideas about domino gates. Domino gates are implementations of logical operations using toppling dominoes to represent the movement of information (bits). The actively toppling domino represents a logic one, and absence of toppling represents logic zero. The domino model can be used as a representation of single-shot wave gates in unconstrained media, such as sub-...

The need for faster circuits in smaller area with lower power dissipation has made it a common practice to use the domino CMOS in high performance integrated circuits. However this improved performance comes at the cost of lower noise immunity. Also current trends in integrated circuit technology have increased chances of crosstalk due to capacitive coupling. Though several works have investiga...

Lotus Domino has been the leading server side software for Groupware applications for a few years now. So far, an investigation of the architectural details of Domino from a performance perspective has not appeared. In this paper, after a brief discussion of the architectural details of Domino 4.6.4 and 5.0, we compare the performance of these two versions of software for different applications...

The straightforward and efficient synthesis of complex aza- and carbobicyclic compounds, which are of importance for medicinal chemistry, is a challenge for modern chemical methodology. An unprecedented metal-free six-step domino reaction of aldehydes with malononitrile was presented in our previous study to provide, in a single operation, these bicyclic nitrogen-containing molecules. Presented...

A novel connection between digit-serial computation and skew-tolerant domino circuit design is exploited to create very efficient implementations of FIR digital filters. In our approach, a digit size of N bits is mapped onto an N-phase overlapping clocking scheme in such a way that N bits are processed in each full clock cycle. In addition, a VHDLbased verification strategy is used to capture t...

A new contention-free Domino logic (CF-Domino) that is especially suited for low threshold voltage (LVT) is reported. Its superior noise margin and speed over conventional Domino circuits for LVTs are demonstrated using HSPICE simulations and a 0.25pm CMOS technology with a supply voltage of 2.5V. The impacts of the new technique on dynamic and leakage powers and area are also presented. Q . an...

Yen, H.-C., A multiparameter analysis of domino tiling with an application to concurrent systems, Theoretical Computer Science 98 (1992) 263-287. The complexities of two domino problems, namely the (n, k) domain problem and the (n, k) 2-person domino game problem, will be investigated with respect to parameters n and k simultaneously. The former concerns itself with tiling a rectangle of width ...

Domino logic is a CMOS-based evolution of the dynamic logic techniques. It allows a rail-to-rail logic swing. It was developed to speed up circuits. In integrated circuit design, dynamic logic (or sometimes clocked logic) is a design methodology in combinatorial logic circuits, particularly those implemented in MOS technology. This work is oriented towards implementing the domino logic circuits...

DOMINO gates are more vulnerable to crosstalk-induced functional failures compared to static CMOS gates. Previously developed noise models generate pessimistic noise analysis because the effect of keeper in DOMINO is not properly incorporated. In this paper, a new crosstalk noise model is proposed for DOMINO logic gates. Our noise model takes the effect of keeper into account and provides more ...

We describe a method to clock the domino pipeline at the maximum rate by using soft synchronizers between pipeline stages and thus allowing “time borrowing,” i.e., allowing input signals to arrive at a pipe stage after the clock tick. We show a robust way of placing “roadblocks” (equivalent to slave latches) in each pipe stage to maintain the optimal clock rate. As explicit latches are not requ...
